Digital mapping of the French media ecosystem

The mapping of the French media ecosystem aims to produce a technical infrastructure to monitor the media landscape's news information and circulation dynamics. We produced a database comprising a large sample of major authoritative news media and alternative sources. Using a global and structural approach, we analyzed the relationships between the French media sources regarding their authority, ideological position, and audience. We also used De Facto’s enriched database of fact checks, the statistical and topological properties of Twitter accounts regularly sharing misinformation to measure their activity and visualize their position in the media ecosystem. First, we present the protocol and the methodology used to produce the dataset, then we describe the general structure and the properties of the French media ecosystem with a specific focus on disinformation.
